I would share a screen shot but it's locked up.
An update is rolling out now.
Make sure the tool is connected to Wi-Fi.
When it starts downloading the update, you will see a down arrow icon at the top right of the screen to the left of the Wi-Fi signal strength icon.
If you press the power button when it is downloading the update, it will prompt you to leave it connected to power and Wi-Fi to get the update more quickly. It must remain on to continue downloading the update. If you do power off, it will continue downloading the next time it is powered on and connected to Wi-Fi. The download will pause at times when scanning a vehicle so once it starts downloading, leave it on connected to power and Wi-Fi when not in use so the download can be completed more quickly.
You can see the progress of the download if you select Tools> Software updates. When the download is complete, the down arrow icon at the top right of the screen will change to a checkmark.
